Rotax 912 oil tank crush washer.

[danny_galaga]

I was going to do an oil change this weekend, but realised I don't have a new crush washer for the oil tank, which it's recommended to change. I have a feeling my oil tank just has a copper washer, but I could be misremembering it. What are people's experiences here? Can a copper washer be substituted? If I need the crush washer, where are people buying them from?

As long as it hasn’t been over tightened before you’ll most likely be able to reuse it. If you can’t get you hands on one and it’s solid metal it could be annealed and reused.

My experience with purchasing Rotax parts is you could save a few bucks by buying an assortment box of sump plug washers from your local automotive part supply.

If the washer has a neoprene seal inserted then a hydraulic parts supplier should have one.

Reuse original one this time, make sure you use two spanners on drain nut. One for can hex and one on drain nut and undo between spanner forces.

It should be a "copper crush washer".

Yes any correctly sized sump style washer, can be substitutes  eg soft aluminium, solid copper, neoprene, etc.

The above washers can be purchase from almost any auto accessory supply store.

I purchased my "stash" from Floods at the same time that I purchased oil filters. I get x3 washers to filters, as I use the same crush washer on the magnet and I practise 50 hr oil changes, filter at 100 hrs.😈
